Privacy Policy
- Blockr watches network connections entirely on your Mac. What it sees — which app connected, to which host and port — is recorded only on your machine and is never uploaded.
- No analytics, no telemetry, no accounts. The app never reports usage and never sends your traffic anywhere.
- Blockr does not read your traffic. It decides at the moment a connection opens; it never inspects, decrypts, or proxies what flows through it.
- The one thing that can leave your Mac is an optional reverse-DNS lookup, which asks your normal DNS resolver for the hostname of an address you are already connecting to. You can turn it off.
- If you buy a commercial license, that purchase happens here on the website (payment handled by Stripe) — not in the app.
1. Who We Are
Blockr is made by twoplus11 LLC, a Missouri limited liability company (twoplus11.com). When this policy says "we," "us," or "our," it means twoplus11 LLC.

2. Data We Do Not Collect
Blockr sees a great deal about your Mac by design — so it is worth being precise about where that stays:
- Nothing is uploaded, ever. The record of which apps connected where lives only on your Mac. It is never sent to us or to anyone else, and Blockr has no way to transmit it.
- Blockr does not read the contents of your traffic. It makes a decision when a connection is first opened, based on the app, the host and the port. It never inspects, decrypts, records, or proxies what flows through — after the verdict, the data path is untouched.
- No analytics or telemetry. The app does not phone home, report usage, or check for updates.
- No accounts at all. Blockr needs no sign-up and no key — there is no login screen and no activation step, for personal or commercial use.
- The app never contacts our servers. Updates are not checked for automatically; you download a new version yourself when you want one.
3. What Blockr Stores On Your Mac
Blockr keeps a few things on your own machine so that it is useful across launches. None of it is transmitted anywhere. All of it is yours to delete.
- A connection log — the app, executable path, remote host, port, verdict and time for each connection Blockr observed, capped at a limit you choose in Settings (5,000 by default). Stored at
~/Library/Application Support/Blockr/history.json. - Per-app totals — how many connections each app made, how many were blocked, and when it was first and last seen. Stored alongside the log in
stats.json. - Your rules — the per-app and per-host decisions you have made, kept in Blockr's preferences so the filter can enforce them.
- Your settings — such as the default action, the alert timeout, and whether hostname lookups are enabled.
You can clear the log and the totals at any time from Settings ▸ History ▸ Clear History, which deletes both files; your rules are kept separately and can be removed from the Rules screen. Deleting the app and those files removes everything Blockr has recorded.
Hostname lookups. To show apple.com instead of 17.253.144.10, Blockr can perform a reverse-DNS lookup for addresses that appear on screen. That query goes to whichever DNS resolver your Mac is already configured to use — not to us — and only for addresses your Mac was already connecting to. Results are cached, and the whole feature can be switched off in Settings ▸ History.
4. If You Contact Us
If you email us — for support or a question about your commercial license — we receive your email address and whatever you choose to put in your message. We use that information only to reply to you. We do not sell or share it.
5. Downloading the App
Blockr is downloaded from our website, which is hosted by a third-party web host. Like any website, the host may keep standard server access logs (such as IP address) for security and operational purposes. This happens at the web-server level when you visit the download page — the Blockr application itself does not transmit anything.
6. Children's Privacy
Blockr is not directed at children under 13, and we do not knowingly collect personal information from children under 13.
7. Your Rights
If you are in the European Union, United Kingdom, or California, you may have the right to access, correct, or delete personal data we hold about you. The only personal data we hold is what you send us by email and, for commercial-license holders, the company name and email tied to your purchase. You can exercise these rights by contacting jeremy@twoplus11.com. We will respond within 30 days. Your commercial-license record is what evidences the license, so deleting it also ends the license.
8. Changes to This Policy
We may update this Privacy Policy from time to time. We will update the "Effective date" at the top of this page when we do. We encourage you to review this page periodically.
